During the Armchair Expert podcast, Prince Harry opened up on mental health, life in the Royal Family, parenting and his approach to royal duties in the 20s. Some of his most blistering remarks show the Duke of Sussex is "starting to be himself" after quitting the Firm as a senior royal, according to Ms Vine.
Recalling some royal watchers had in the past accused Meghan of changing the Duke of Sussex, Ms Vine wrote in the Mail on Sunday: "I don't think she's the only one to blame.
"I believe Harry is just as complicit. It's only that we've never really wanted to accept it because in our minds he is still that tragic young boy at his mother's funeral.
"But that Harry is gone now and the man we see before us is a very different kettle of fish.
"Far from being brainwashed by Meghan, I think he's just starting to be himself."

Ms Vine noted that Harry had already spoken in the past, and in particular while serving in the Army, of his reluctance at being a royal.
However, she claimed, during his latest public appearance he clearly laid out the feelings towards the Firm he has been harbouring for years.
The move to the US away from the Royal Family, Ms Vine added, may have been carried out to pursue the Duke's "dream of freedom" - at a great cost for the Crown.
She said: "Harry has always claimed he stepped down as a working royal and moved to America to protect his own family.

"That he had no choice, that it was the only sane option. But if you ask me it's got nothing to do with that.
"He did it to pursue his dream. His own dream of freedom – which is fast becoming the Royal Family's ultimate nightmare."
Speaking to the podcast host, Dax Shepard, Prince Harry said in his early 20s he didn't want to take on royal duties.
He said: "In my early 20s, it was the case of 'I don't want this job, I don't want to be here, I don't want to be doing this, look what it did to my mum.

"'How am I ever going to settle down and have a wife and a family when I know it's going to happen again.
"'Because I know, I've seen behind the curtain, I've seen the business model, I know how this operation runs and how it works, and I don't want to be part of this'."
Only therapy, he said, helped him to make the best out of his situation and use his privileged position to help others.
The Duke also likened life in the Royal Family as "a mix of the Truman Show and being in a zoo."

Speaking about the portrayal of princes and princesses on TV and how it compares to his experience, the Duke of Sussex relayed Meghan's "most amazing explanation".
He continued: "You don't need to be a princess, you can create the life that will be better than any princess.
"And that's coming from her own lived experience."
Moreover, he spoke about bringing up his children in a different way than his dad Prince Charles, in an apparent criticism of his own upbringing.

He said: "I don't think we should be pointing the finger or blaming anybody, but certainly when it comes to parenting, if I've experienced some form of pain or suffering because of the pain or suffering that perhaps my father or my parents had suffered, I'm going to make sure I break that cycle so that I don't pass it on, basically.
"It's a lot of genetic pain and suffering that gets passed on."
Parents, he said, should try to stop this passage from happening.
He continued: "I started to piece it together and go 'okay, so this is where he went to school, this is what happened, I know this about his life, I also know that is connected to his parents so that means he's treated me the way he was treated, so how can I change that for my own kids?'"
